Let's simplify step-by-step. 7−4(3−(4y−5))

Distribute: =7+(−4)(3)+(−4)(−4y)+(−4)(5)=7+−12+16y+−20

Combine Like Terms: =7+−12+16y+−20=(16y)+(7+−12+−20)=16y+−25

Answer: =16y−25

7 - 4[3 - (4y - 5)]
= 7 - 4[3 - 4y + 5]
= 7 - 4[-4y + 3 + 5]
= 7 - 4[-4y + 8]
= 7 + 4*4y - 4*8
= 7 + 16y - 32
= 16y - 32 + 7
= 16y - 25

What is the slope of the line shown below?

Harman [31]

Answer:

Step-by-step explanation:

Slope is often called rise/run.

This is the amount the line goes upwards, rise, compared to the amount it goes sideways, run.

Compare the two shown points. From the left point the the right, the rise is 6, while the run is 3, creating the rise/run of 6/3. This is simplified to 2.

Solve the following equations for 0 ≤ theta ≤ 360º cosec(2 — 45°) = 2

lions [1.4K]

Step-by-step explanation:

here ,

$cosec \alpha = \frac{1}{ \sin( \alpha ) }$

now,

cosec(2-45°)=2

or,

1/sin(2-45°) =2

or,

1/sin2cos45°-cos2sin45=2

or,

$\frac{1}{ \sin(2) \frac{1}{2} - \cos(2) \frac{1}{2} } = 2$

or,

sorry I have that much qualifications to work on this question and hoping this much will make bit easy for you to solve it further

In a survey conducted by TheKnot.com, 1165 engaged or married

I am Lyosha [343]

Answer:

$559\frac{1}{5}$

Step-by-step explanation:

We want to determine the exact value that is 48% of 1165.

Now 48% = $\frac{48}{100}$

The term 'OF' means multiplication.

Therefore:

48% of 1165 = $\frac{48}{100}X 1165$

= $\frac{55920}{100}$

= $559\frac{1}{5}$

=559.2 in decimal form.

The exact value that is 48% of 1165

is given as $559\frac{1}{5}$ or 559.2 in decimal form.
